3nventor attorney Patented May 31, 1932 UNITED STATES,


Application filed August 3,1929, Serial n 383,307, and in Italy Au ust,9,i9as-.

This invention relates to a security device adapted to prevent robbery of motorcars, and has for its object to provide a device of the kind referred to, comprising a mechanical'stopping device acting on the brake operating system of the car, said device being preferably adapted to control anelectric security or alarm arrangement, the electrical equipment of the car being suitably modified in accordance therewith. I

According to the invention, the mechanical device consists of a displaceable member adapted to lock the brake levers in their on position and to be locked by the spring operated'bolt of a lock, the latter being capable of being released only by means of its key proper; said member, during its travel to its said locking position, preferably operating a change-over switch in the electrical equipment of the car in order to commute a liner button of the motor the horn will be caused to ring.

In the annexed drawings, showing by way of example and diagrammatically one way of carrying out this invention, as applied to a car having front and rear brakes,

Fig. 1 is a side view of the security device,

viewed as a whole on an engine-and-gear box I body of a car, I V I Fig. 2 is a plan view on an enlarged scale of the device,

Fig. 3 is a cross sectional view according to IIIIII of Fig. 2, and p or V Fig. 4 is a partial electric diagram of the supply circuits of the car, as modified for use in connection with the invention.

Referring to the drawings, 1 is a displaceable member adapted for instance to be operated by means of a pinion 2 andrack 3 fixed thereon, so as to be brought to lock the brake levers in their on position, against-the action of a spring 12; Intheembodimentshown, the pivot 4 of the pinion 2 is provided with a cross pin 5 and is operable by means of a button or handle 6- upwa-rdly projecting through the floor of the car so as to bewithin easyreach of the driver, said button having a bushing with a suitable; bayonet slot engaging said pin. lock? is'provided, having its boltfl8 adapted to abut againstthe'side of the member 1 chi-r Sideways of' the 'sli-dabl'e member a 1.

ing its operative travel in the direction shown by the arrow in Fig. 2, and to engage a stop on'the slide, as for instance to enter-an opening 9 in the flange of the slide, said bolt being preferably automaticallyymoved to its stop en aging piositi'onflby the action of a spring, Qnotjshown). II I I I A -DL 1ring itsfltravel in the'direction of the arrowth'eflocking member I mayoperatasa'y through aproj'ecting pin 10;a change-over switch ll'so as to-modify the electricalci-rcuit on the car. Said circuitfas well as the change-over device to be used, are shown only diagrammatically in Fig; land may be ofany I suitable design,

The operation is as fol-lows 2 Once the brakes are applied, the

the direction indicated by the arrow in Fig;

buttonv V is operated soas to displace the member 1' in I 2, so'as to bring it inthe path of some mov-V able member of the brakes, and/or "tocooperate therewith, when the bolt 8 will engage the stop inv themember I. Preferably the slidable inember is'madetoabut against the rocking lever simultaneously operating both the front and rear brakes. A y

,At thxe same time, dueto the displacement of 'member '1, the part Il -O'will operate the change-over switch- 11, so that the la-tterwi-ll I commute-the electric horn-K the circuit of the" starting motorM over the suppl y the motor will then'cause thehorn to, toot,

giving the alarm-at the same timeit warms be possible to actually excite the starting mo tor and to; have the engine; started.

. When itis'desired' toip'ut the car in the usual operativecon ditlons it will be suflioient to release the lock 7, thus causing the bolt 8 to be disengaged from the member 1, so that all the parts under the action of spring 12 Will take again their starting position. The brakes Will thusbe once more releasable by the normal action of the brake-lever, and the normal ignition circuit being restored,

V as shown in Fig. 4, it Will bepossi-bleto op erate the starter and'to supplythe ignition distributor. V

The operativeend of the slidable member 1 may be provided With anadjustable head,

so that the length of member 1 may be ad- "justed according to the. variations in the stroke of the 'rockinglevers of the brakes, as well as, according to conditions to be met in the different kinds of motor cars .to which f the device of the invention is to be applied. -If desired,-the mechanical device shown in Figures l, 2 and 3' may be used independentlyof the modification in the electric equipment shown in Fig. 4, Without departing fromthe scope of the invention. 1 i

I claim:

v1; In a motor car a rocking lever of the brake operating system, a barslidable in the plane of movement ofsaid lever, adapted to obstruct the return movement ofsaid lever y from its onto its off.."p,osition, agvrack integral with said bar, a pinion engaging and operating said rack, means'for locking'said i ClGVlCGlll its operatlve position, aspringautomatically returning said movable member i to, its inoperative position,- When said memintegral With said bar, a pinion engaging her is released by sa'id' locking means, and a knob'proj ectingthrough the floor of said car for operating said pinion. 5

2. In a motor car a rocking lever. of the brake operating system, abar slidable in the plane of movement of said lever,'adapted to obs-tructthe return, movementof said lever from its-on. to its off position, a rack and operating-said rack, a stop' on said bar,

- a lock comprising a bolt movable transversely of said bar, adapted to engage saidstopwhen said'bar is moved to its operative position, anda knob projecting through the floor of said car for operating said pinion.

.3. In ainotorl car a rocking lever of the brake operatin'g'system, a bar slidable in the plane of movement of said "lever, adapted to obstruct the return movement .of said lever fro'mits,10n to its off position, a rack integral with said'bar, a pinion engaging and operating said rack, a'stop on said l bar, a lock comprising a springactuated bolt movable transversely of said bar, adapted to automaticallyengage said stop when said bar is movedgto its operative position, a spring automatically -=returning said bar to its inoperative position when said barjis released by said bolt, and aknob projecting through the floor of said car for operating said pinion.
